LT; azam'amy Miami Be it known that I, LEONZORNSTEIN, a

citizen of the ,United States of America, residingatBrooklym-in the county of Kings and StateofvNew'York, have invented cer tain new and usefulImprovements in Processes ofMakinga Paint or Enamel'Material, "OfWhiOll: the following is a specification.

My invention relates to a novel paint and enameling material, and to the process of producing-the same. 'The material contem-.

' plated by ;my invention is an oil-like body,

or as a grinding oil-for pigments.-

which is capable of :bingused either alone,

M In practising the invention I employ phenols, or phenolic; bodies, and at the initial stage of the. process, I polymerize 'such phenols, the polymerization being efl'ected as desc 'bed in-United States Patent 526,786

to Manasse, and in United States -Pat'ent 812,608to Stephan. :The commercial practics of the invention involves the production of two substances, for convenience. of description termed substances A andB, their subsequent admixture in suitable proportions, and finally their mixtureeither sepa rately or together, with about five per cent.

of a concentrated solution of a salt, such as chlorid, nitrate, sulfate, or the like, whereby the final product results.

It will be understood that I am not limited to proportions of admixture, to specific kinds of substances used, or to the length of treatment, and with this statement in mind, the following example will enable those skilled in the art to practise the invention.

Substance A. Dissolve in a suitable tank 100 parts, by volume, of cresol in 100 parts of lye, containing approximately six per cent. of caustic soda, and thoroughly admix therewith seventy-five arts of forty per cent. formaldehyde solution. Allow the mixture to stand for approximately twelve hours, and then gradually add to it one hundred parts of a ten per cent. solution of commercial hydrochloric acid, the mixture being. continuously stirred. When this mixture is permitted to settle, substance A precipitates out of the specification of Letters 1 mm;

heavier than water.

same in the form. of.ai yellowish liquid,

In a suita'ile dissolve one hundred parts, by volume, of cresol in one hundred parts of lye containing, approximately six per cent. of caustic soda, fthen add sixty parts of forty per cent; of formaldehyde solution, stirrir gthe mixture vigorously. Heat themixture untilitcomes to a boil, then discontinue leating, and gradually add fifteen additional parts of formaldehyde solution which n sultsin the generation of sufiicient heat-to continue the boiling for a time. When. the boiling subsides, the. solution is clear and" yellow incolor Add thereto a ten per cent, solutionoi-hydrochloricacid as is donew th substance A, and the result is a liquid p1 ecipitate. which-is substance B, resembling s1 lbstance A, but heavier in body.

Find product.

To obtain the final productsubstanee B is mixed with approximately twenty-five'per cent. of sub ;tance A, yielding an oil-like body which, when allowed to stand, becomes substantially free from water. I then add about five p. r cent. of a concentrated solution of an acid salt, which accelerates the hardening oi the oil and gives it the desired shade of 0010 r, dependent upon the character of acid salt employed. This final product is an excellt nt 'medium for grinding with pigment, mi: res readily with practically all the solvents used in the manufacture of spirit enamels, and dries hard when baked ments, and thinned with any suitable t mning substarcm'it is adapted for use as a transparent :olored enamel.

What I cl: rim as new and desire to secure by Letters Patent is 1. The herein described process of manu-' facturing .a paint and enameling material, which consists in forming a mixtureof a phenol solution, an alkali, formaldehyde,

and a solution of hydrochloric acid, and settling said mxxture to obtain an oil-like pre cipitate therefrom, thereafter forming a mixture of a henol solution with an alkali and formald yde, heating said mixture to the boiling point, a quantity of formaldehyde thereto,'prec1pitating an oil-like bod out of said second mixture, and finally com ining the oil-like. precipitates of the first and second mixtures, substantially as described.
